[PATCH] D84414: [RISCV] Support Shadow Call Stack

[Jessica Clarke via Phabricator via llvm-commits]

jrtc27 added a comment.

Is there a reason for choosing X18? On AArch64 that's either a temporary or saved register depending on ABI, but determined to be the "platform register". Picking X18 on RISC-V because that's the same index as AArch64 seems a little arbitrary, but maybe it happens to make sense.
